Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension is developed for teachers, to help them keep the noise in the classroom at a decent level, using gamification.

==How does it work==

For each minute the noise level is under the set threshold, you receive a smiley.

For each minute the noise level is higher than the threshold, you receive a grumpy.

Total number of points is total smileys - total grumpies.

First, you have to set the desired threshold (from 0 to 120dB) in SETTINGS.
